INVENTOR. Z7 J'a5ep qlekq 'fi ZZI BY 1 V I I 7 d w 9 w v ATTORNE- Patented Feb. 28 1933 UNITED STATES JOSEPH PALERMITI, or m, MICHIGAN RADIATOR Application filed September 4, 1931'; Serial Ho. 561,179.

My invention relates to a new and useful improvement in a radiator used for heating purposes and particularly adapted for use in steam heating systems.

It is an object of the present invention to provide a device of this class which will be simple in structure, economical of manufacture, durable, highly efficient in use, and provided with a maximum radiating surface.

It is another object of the present invention to provide a radiator of this class whereby the inner surface of the inlet and outlet pipes will lie flush with the base of the radiator so that an accumulation of condensation in the radiator will be prevented;

Another object of the invent-ion is the provision in a radiator of this class of bafiie plates mounted in the radiator and so arranged as to permit an efficient travel of the 29 heated medium through the radiator.

Other objects will appear hereinafter.

The invention consists in the combination and arrangement of parts hereinafter de scribed and claimed.

The invention will be best understood by a reference to the accompanying drawing which forms a part of this specification, and in which,

Fig. 1 is a perspective view of the invention.

Fig. 2 is a longitudinal vertical sectional view of the invention.

Fig. 3 is a fragmentary sectional viewtaken on line 3-3 of Fig. 2.

Fig. 4 is a View taken on line 4L of Fig. 2, with parts broken away.

The invention is intended as a cast metal radiator which is preferably cast in a single piece thus permitting an economical fabrication and installation of the invention.

The structure comprises oppositely disposed side walls 7 and 8 each of which is provided with the outwardly bulged spaced portions 9 which serve as radiating fins and provide the comparatively shallow compartments 10. Similar bulges 11 providing the comparatively shallow compartments 12 are formed on the top wall 13, the base or bottom 14 being flat except at its opposite ends where it is provided with an outward bulge 15 to provide the necessary body for thethreaded opening 16 in which the inlet oroutlet pipes 17 .and ll8 are threaded. By providing the: bulge or boss 15 on the bottom orbase 1 1, "itbecomes possible to mountthe outlet pipes with their inner surface flush with the inner surfaceof the bottom or base 14 so as to prevent an accumulation of condensationwithin the radiator. 7

Positioned within the main body of the radiator are the inclined spaced b'aflie plates 19 and 20 which are spaced from the bottom 14 and the top 13 and also terminate at their ends in spaced relation to the end walls 28 and 29. Formed in the end wall 28 is a threaded opening 21 in which may be mounted the relief valve 30. A similar opening 22 is formed in the end wall 29 and when no relief valve is mounted therein thesame is closed by the plug 23. The core openings 24: and 26 are also closed by the plugs 25 and 27. The baflle plates 19 and 20, while serving to direct the fiow of the heating medium through the radiator, also serve as a reinforcement of the structure. On this account, the structure may be made of comparatively light material and still be sufficiently strong to withstand all normal pressures.

Detachable legs 33 and 34 are mounted o the radiator as a support. 7

With a radiator constructed in this manner, an easy casting of the same may be effected which will result in a cheap construction while at the same time due to the presence of the radiating parts described, a very as efficient radiator is provided. No rough, uneven, or parts difiicult to reach are present so the device may be easily cleaned and the accumulation of dust etc., prevented.

While I have illustrated and described the preferred form of construction of my invention, I do not wish to limit myself to the precise details of structure shown, but desire to avail myself of such variations and modifications as may come within the scope of the appended claims. 7

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

1. In a radiator of the class described, a

hollow body for the reception of heating fluid; a plurality of spaced outwardly bulged portions forming radiating fins on said body and communicating therewith, said body being provided on its inner surface with shallow compartments along each of said outwardly bulged portions; and a plurality of baflie plates positioned in said body in superimposed spaced relation and extending from side to side thereof and terminating inwardly of each of the ends of said body, said compartments being free from bafiles.

2. In a radiator of the class described, a hollow body for the reception of heating fluid; a plurality of spaced outwardly bulged portions forming radiating fins onsaid body and communicating therewith, said body being provided on its inner surface with shallowcompartments along each of said outwardly bulged portions; and a plurality of battle plates positioned in said body extending from side to side thereof and terminating inwardly. of each of the ends of said body and inclined toward each other and toward the horizontal. a

In testimony whereof I have signed the foregoing specification.
